Electric Vehicles

The Best Part of an EV Is When You’re Not Driving

That enormous battery can do a lot more than propel your car down the road.

Many new cars and trucks come with modes to optimize driving. Anyone who’s watched an episode of Top Gear has seen the hosts extoll the virtues of sport mode, which makes steering tighter and more responsive, or off-road mode, which allows a 4X4 to better cross muddy terrain.

Electric vehicles have their own performance modes, like Tesla’s “launch control” that sends the Model S screaming off the starting line. But some of the most interesting things an electric car can do happen when it’s sitting still. Because the giant battery along the bottom of an EV can do a lot more than propel the car down the road, EV-makers have realized they can use this reserve of electricity to create quality-of-life features that wouldn’t be possible in gasoline cars.


There used to be a set of no-nos when it came to sitting in the car. Running the air conditioner, listening to music, or leaving the headlights on without the motor running would tax the boxy 12-volt battery found under the hood. Overdo it and you might need to talk a stranger into a jump-start, something I learned the hard way when I was a pre-teen and depleted the battery in my parents’ Pontiac minivan waiting for them to escape a meeting.

Cars got better about this issue as the years went by, but electric vehicles nearly negate the problem entirely. Consider the modern sin of leaving one’s pets behind. States like California have laws against leaving an animal unattended in a hot car, and for good reason — without ventilation, a vehicle interior can get even hotter than the outside air. Combustion cars can’t (or shouldn’t) keep the air conditioner on without also running the engine, which prevents you from keeping the pooch nice and cool.

Not so in the EV age. Rivian and Tesla both have pet modes that will use the battery’s electricity to run climate control while you run into Walgreens while Walter the terrier stays behind. Both brands display a cheery cartoon dog on the large center touchscreen, alongside a message to would-be Good Samaritans that the cabin is holding a pleasing and pleasant temperature.

Pet modes come with safeguards. They can’t be used if the battery is too low, for example, to prevent a scenario in which the car runs out of juice and can no longer cool the dog. Still, they can’t guard against the fact that this new technology runs against a societal stigma against leaving pets in the car. (I keep paper signs in my Model 3 that read “AC ON, DOG IS FINE” to dissuade passersby from breaking a window or calling the authorities.)

Humankind benefits from EV climate features, too. Leaving the heat or AC on indefinitely bleeds a few miles of range from the battery, but doesn’t endanger your ability to get the car started again. You could even sleep in the comfort of a climate-controlled room on wheels (or park cranky kids in front of Encanto on the touchscreen). Tesla offers Camp Mode for this very purpose, promising that an entire night uses only about 10 percent of the battery. Rivian’s is especially high-tech: It tweaks the truck's suspension to keep it level on uneven ground, and allows owners to shine their headlights to illuminate the campsite, a definite battery-killer in a combustion car.


These applications are mere extensions of the familiar, giving traditional car accessories a lot more staying power. The transformative potential of driving a battery on wheels would be the ability to use that electricity supply for, well, anything you want.

The technical name is bidirectional, or two-way, charging. The Ford F-150 Lightning includes this feature, and its advertising touts that the electric truck can plug into your home to provide days of backup power in the event of a blackout. Tesla’s initial round of Cybertruck marketing proclaimed that the steel beast would become the mobile heart of a jobsite, with power tools running on battery power thanks to an array of outlets on the vehicle’s exterior.

Two-way charging makes an EV more technically complex, since the direct current (DC) power the car uses would need to be transformed back into alternating current (AC) to run other applications. But the possibilities are enticing for the electric vehicle owner. EVs that remain plugged in while not in use could feed energy back onto the electrical grid, just as homes with solar panels can pass on excess energy. Such a setup could help avoid blackouts by creating an alternative source of stored electricity — not to mention generate income for EV owners who are technically selling power back to the grid.

It is coming, if slowly. Tesla, having resisted bidirectional, said this spring that it would adopt the technology within a couple of years. Other automakers have introduced some limited versions of it.

Someday soon, then, your car, flashlight, and backup generator may be one and the same.

Exclusive: Over 530 Local Laws Now Seek to Ban or Restrict Data Centers

The overwhelming majority of the ordinances were enacted this year, a Heatmap Pro review shows. They’re helping to drive an unprecedented surge of data center cancellations.

America’s data center backlash is gaining steam.

Anti-data-center protesters briefly interrupted President Trump’s speech at a General Motors facility in Michigan earlier this week. A day later, the country music legend Willie Nelson called on Americans to “fight against data centers invading our land.”

Washington has yet to pass major data center regulation. But the backlash is already reshaping local zoning and land use codes across the country, according to an extensive review of public records conducted by Heatmap Pro. A surge of new restrictions and bans have killed dozens of proposed data centers this year.

More than 500 counties or municipalities now actively restrict or block new data centers, according to the review. This tally includes only the most severe constraints — such as steep setback requirements, impossible noise limits, or outright bans on permit approvals — that all but forbid the construction of a data center.

The overwhelming majority of these restrictions have been enacted since the beginning of the year. Nearly 190 have been passed since June 1.

The pace of moratoriums is “accelerating,” Peter Freed, a founding partner at the Near Horizon Group and the former director of energy strategy at Meta, told me.

Broadly, these new local restrictions seem to be succeeding. More than 50 data centers have been canceled so far this year after facing local pushback of some kind, according to a Heatmap Pro review of press accounts, public records, and project cancellations.

That’s more than twice as many projects as were canceled under similar circumstances in all of 2025, according to our data. Eight projects were canceled in July alone.

Ominously for developers, the rate of projects facing cancellations seems to be increasing over time.

1. Commonwealth Fusion Systems raises another $1 billion

Last month, I toured Commonwealth Fusion Systems’ headquarters in small-town central Massachusetts. The place was abuzz in activity. On the factory floor side, workers were assembling the magnets needed to ultimately form the torus-shaped reactor — think a giant doughnut with an interior that curves like the core of an apple — called the tokamak. On the actual reactor side, SPARC — the prototype that CFS expects will make history next year as the first private enterprise and only tokamak to ever generate more energy that it took to start the fusion reaction — was starting to look like a functional machine from my view on a second-story walkway overlooking the sterile assembly room. The old joke that fusion is the energy source of tomorrow — and always will be — certainly didn’t ring as funny now. I’ll tell you who isn’t laughing: All the new investors that just poured another $1 billion into CFS. The company announced its latest funding round early this morning, which brings the startup’s total fundraising since its launch as a spinout from the Massachusetts Institute of Technology in 2018 to $4 billion. CFS now accounts for 30% of all the private capital that has flowed into fusion. What distinguishes this round, my colleague Katie Brigham wrote, is that the money is coming from a bunch of institutional investors, such as pension funds and sovereign wealth funds, rather than venture capitalists. On a call with reporters this week, CFS’s newly-named chief financial officer, Lorence Kim, said it’s the first-time institutional investors comprised the majority of the new funding. When I asked the company’s spokeswoman for a percentage estimate breaking down the new versus old investors in this round, she declined to comment. Kim cautioned that the funding isn’t the kind of capital you raise before launching on a stock market. But his hire is notable. The former Goldman Sachs banker famously helped take the pharmaceutical giant Moderna public and held the top financial role through the start of the Covid-19 pandemic.

Commonwealth Fusion Systems Wins Over New Class of Investors With $1 Billion Raise

Risk-averse but deep-pocked institutional investors join the party.

Commonwealth Fusion Systems Wins Over New Class of Investors With $1 Billion Raise

When the Fusion Industry Association surveyed the sector earlier this month, it found that the industry’s 56 active companies had collectively raised more than $14.2 billion over the past five years. But an ever-larger share of that money is ending up in the hands of one startup: Commonwealth Fusion Systems.

With its latest $1 billion funding round, announced today, the MIT spinout now accounts for nearly 30% of all capital in the industry. The new financing, led by a wave of institutional investors entering the sector for the first time, will support construction of the company’s first commercial power plant in Chesterfield County, Virginia, which CEO Bob Mumgaard says is on track to come online in the early 2030s.
